HU not working through harness.

Yet another "the wires sparked and now the HU doesn't work" thread. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I tested the HU to the battery, and everything lights up. After the wires sparked, my Jeep needed a jump. This happened once before, and I brought it to my fathers friends dealership and they had a hard time figuring out the problem, or so it seemed.

What can I look for to avoid goin back to them? It would most likely be a fuse right, not a whole new wiring system.

Which fuses should I look at? I've checked the HU fuse, and the radio fuse on the inside panel. That's all.

That's all.

Did you just look at them or did you test them to verify current?
